Tunis: As the capital, Tunis offers excellent 4G and growing 5G coverage across the city center, business districts like Berges du Lac, and historic sites such as Carthage. Connectivity is generally stable on the above-ground Métro léger light rail system. Signal strength may slightly decrease within the dense, narrow alleyways of the Medina or deep inside older buildings.

Sousse: You'll find strong and reliable 4G connectivity throughout this coastal hub, especially along the beachfront, in the modern Port El Kantaoui marina area, and around the Ribat. While outdoor coverage is excellent, the signal can be weaker inside the thick stone walls of the historic Medina or in the lower levels of large resort hotels.

Hammamet: Coverage is very good across Tunisia's premier resort town, with robust 4G service in both the historic Medina and the modern Yasmine Hammamet tourist zone. The signal is optimized for the main hotel and beach areas. Connections may be less consistent in the rural hinterland just outside the main town.

Djerba: The main tourist areas on the island, including the town of Houmt Souk and the northeastern coastal hotel zone, have dependable 4G coverage. Mobile data performance is strong in these populated areas, but the signal can become intermittent as you travel into the more rural and sparsely populated interior of the island.

Autoroute Expressways: The main A1 (Tunis-Sfax-Gabès), A3 (Tunis-Béja), and A4 (Tunis-Bizerte) autoroutes generally offer stable connectivity, especially in the densely populated northern and coastal Sahel regions. Signal can become less reliable on the A1 south of Sfax as it enters more sparsely populated areas.

SNCFT Intercity Trains: The main coastal rail line connecting Tunis, Sousse, and Sfax provides fairly consistent mobile signal. However, trains traveling west into the interior towards Gafsa or south towards Tozeur experience significant and prolonged periods of signal loss between towns.

Dorsale Mountain Region: When traveling through the central and northwestern Dorsale mountain range, particularly on national roads away from the main autoroutes, expect intermittent signal. Coverage drops frequently in valleys and remote forested areas around Jebel ech Chambi and the Kroumirie region.

Southern Governorates & Sahara: South of the Chott el Djerid salt pan, mobile coverage is largely confined to towns like Tozeur, Douz, and Tataouine. Travel between these settlements across the Sahara desert regions involves extensive dead zones with no signal for long distances.
